CAR-COUPLING.

To all whom may concern. 7

Be it known that T, EDMUND P. Krnnn, a citizen of the United States, residing at Alliance, in the county of Stark and State of Uhio, have invented certain new and useful Improvements in Car-Couplers, of which the following is a specification.

My invention relates to couplers of the Janney type which employ a pivot knuckle, a lock therefor and a litter for operating the lock.

The subject-matter of the present application was first disclosed in my application Serial No. 540,733 entitled Car couplers, this being a division thereof.

The general type of lock as shown and described herein was first disclosed in the patent to Janney, Kinne and Trump numbered 905,078, the present application relating not so much to the lock itself as to the anti-creep provisions in connection with a lock of that type.

In the patent above referred to, the lock is provided with anti-creeping provisions which are normally in operative position when the lock is in locking position. In the present invention T have provided the lock with anticreeping provisions which are normally in inoperative position, but which are brought into operative position to prevent further creeping of the lock promptly after the lock begins to creep. The shoulder on the interior of a coupler shank and the hook on the lock,which constitute the anticreeping provision,being normally out of engagement with each other, afford no resistance to the raising of-the look from the rear of its center of gravity in the initial opening movement thereof. Creeping of the lock, however, is effectually prevented because as soon as the forward or looking end. of the lock begins to creep under draft the locking member will rock and the anticreeping provisions are brought into operative relation. Thus further upward movement is prevented.

Referring to the accompanying drawings Figure 1. is a plan view of a coupler embodying my invention, part of the coupler shank being broken away; Fig. 2 is a side elevation having the lower portion of the shank broken away; Fig. 3 is a section on the line 3, 3 of Fi 1., and Fig. 1 is an enlarged fragmentary section showing the lock disengaged from the anti-creep profipecification of Lett rs Patent.

Divided and this application fi1ed May 1,

visions, and, in dotted lines, in engagement therewith.

Referring more particularly to the drawings it will be seen that I employ a coupler having a shank 10, head 11 and knuckle 11-2. The knuckle is pivoted on a pin 13 and is provided with a tail 14. A lock 15 is mounted for vertical swinging movement within the coupler head, the lock being actuated by a projection 16 on a lifter and knuckle opener 17. The member 17 is guided in its vertical movement on a vertically extending rib 18 within the coupler head. In the e1nbodiment shown in the drawings, the lifter 17 is actuated by means of a two-way lifteractuating device having a weighted portion 19 extending within the coupler head and which is adapted to be contacted by the lower end of the lifter 17. The portion 19 is rigidly connected to or integrally with two arms 20, 21 each having operating levers 22, 23 removably secured thereto. The lifteractuating lever is pivoted at 2 1 to an integral part of the coupler head.

The lock 15 is provided with a rearwardly extending portion 15 having off-sets 15 and 15". The part 15 has on its lower edge a hook adapted for cooperation with a shoulder or abutment 10" within the coupler shank. Also within the coupler shank and preferably integral therewith are walls 1O and 10. It will be seen also that the coupler shank, where it joins the head of the coupler, at the point 10, is slightly raised and on this point the portion 15 of the lock 15 is adapted to rest in its normal position and to rock thereon in case of any creeping of the look.

It will be understood by reference to the drawings that the lock is lifted by the lifter 17 at a point to the right of its center of gravity as viewed in Fig. 4. Therefore, during normal operation of the coupler the hook 15 will at no time be in engagement with the shoulder 10 v that the lock begins to creep upward under draft, it will be seen that it will rock on the point 10 and assume the dotted line position of Fig. 4, that is, with the hook in engagement with the shoulder and with the portion 15 of the lock in contact with the wall 10 within the coupler shank. In this way any further upward movement will be prevented, for the reason that the parts are held in locked relation. The hook of the However, assuming lock is located behind the projection 10 and the rear 15 of the lock is pressed against the abutment 10 of the coupler head. However, the lock may be raised by means of the lifter even when in this position, due to the fact that the lifting action is to the rear of the center of gravity of the lock.

The advantage in this construction is that normally the anti-creep provisions are not in operative position but that in view of the fact that the lock always rises from the front during any abnormal creeping, the hook will engage with the shoulder and the lock be prevented from further upward movement.

I claim:

1. In a car coupler, the combination of a draw head, a knuckle, a lock having a floating pivot, located in said draw head, a

shoulder located within said draw head, and means on the rear of the lock normally outof engagement with said shoulder but adapted to be engaged with the shoulder upon the lowering of said rear end to prevent creeping ot the lock, substantially as described.

2. In a'car coupler, a knuckle, a lock having a floating pivot and an anti-creeping hook for said look at its pivotal end, said anti-creeping hook being in inoperative position when the lock is in its normal locking position, substantially as described.
